WIRE-STITCHI NG MACHINEL SPECIFICATION forming part of Letters Patent No. 532,005, dated July 52, 1895.

Application filed December 12, 1894. Serial No. 531,568- (No model.)

To all whom it may concern:

Be it known that we, VVILLIAM A. PHIL- POTT, Jr., of Niagara Falls, county of Niagara, and State of New York, and THOMAS A.

BRIGGS, of Niagara, in the Province of Ontario, in the Dominion of Canada, have invented new and useful Improvements in chines which are employed for binding books by means of wire staples driven throughthe and it has. special reference to the mechanisms for feed book along the line of binding;

ing the wire to the machine and cutting the wire into blanks of the requisite lengths and other auxiliary devices connected to the. machine; and the invention consists in an improved organization of a machine which is superior in its operation of cutting the blanks from a continuous wire, fed automatically to the machine and forming the staples from the blanks and subsequently driving said staples accurately into the book to be bound, and which machine is equipped with convenient and efficient means for adjusting the wire feeding and cutting mechanism, to form staples of different sizes according to the book to bebound, and also possesses various other advantages over prior machines of this class, all as hereinafter more fully described, and summed up in" the claims.

In the annexed drawings, Figure l isaside elevation of a wire-stitching machine embodyingourinvention. Fig. 2 is an enlarged front elevation of that part of the machine which is above the book-supporting table. Fig. 3 is a vertical transverse section on line 1 1 in Fig. 2.

Fig. 17 is an inner face View of the anvil with thewire-blank detainer connected thereto. Fig. 18 is a face view of the 6 staple-former and staple-driver. Fig. 19 is a detached perspective edge view of one of the staple-former plates, showing the attachment of the stop for arresting the inward thrust of the wire blank; and Fig. 20 is a detached face view of the supplemental faceplate of the machine.

Similar letters and figures of reference indicate corresponding parts.

A denotes the standard or main supportingframe of the machine, which frame is formed with forwardly-extending arms A A, disposed one above the other and in the same vertical plane.

On the lower arm A is mounted the table or saddle F for supporting the book to be bound, and to the upper arm A are connected the mechanisms for forming and driving the wire staples employed for binding the book.

The upper armA terminates at its front with a vertically disposed hollow head A' containing the wheel B, which is fastened to the end of the horizontal shaft 0, which extends through the upper arm A and has fastoned to its rear end the driving pulley B.

The cap or face-plate A" of the head A is provided in its inner side with a vertical groove d in which slides the bar. 6, the lower end of which we designate the staple-former 5' which is provided with a vertical slot 6, extending through said end. At opposite sides of this slot are vertical plates 6 e fastened to the bar e and provided in their inner edges with longitudinal grooves, as shown at c""in [03 Fig. 5 of the drawings. Said staple former receives intermittent reciprocating motion by a roller 4", pivoted to the bar e and projecting into a cam-groove Z in the face of the wheel B.

The bar a is formed with avertical guide Z in which slides another vertical bar f, which is connected to the wheel B by a pitman f, which transmits reciprocating motion to the bar f. The point of connection of said pitman to the wheel B is in such a position in relation to the cam-groove Z as to cause the two bars e and fto reciprocate alternately for the purpose hereinafter explained.

The bar f constitutes the staple-driver, which has firmly secured to its lower end a plate f", the vertical edges of which are formed with tongues f' by which said driver slides in the grooves e' of the plates 6'.

To the base of the front of the face-plate A is bolted or otherwise securelyfastened a case D, having its cavity adjacent to said face-plate. In said cavity is supported the laterally-movable anvil (1, preferably formed on the lower end of a bar or hanger a", which is pivoted at its upper end to the case. Said anvil projects from the rear of the hanger and is held normally in the paths of the stapleformer e and staple-driverf. The top of said projecting anvil is beveled or wedge-shaped so as to cause the descending staple-driver to force the anvil out of its way. The anvil a is provided with a transverse slot 19 for the reception of the wire blank from which the staple is to be formed, said blank being fed into a horizontal groove 9 in the case D, as shown more clearly in Fig. 13 of the drawings.

Immediately beneath the anvil a is a staple-supporter a, which is supported yieldingly in both vertical and lateral directions to yield to the downward movement of the staple-driverf and to the contact with the book to be bound. This staple-supporter a we preferably pivot to the lower end of an arm a, which in turn is hingedto the top of the case D at 6 and is provided in its lower end with a slot or, through which the pivotpin of the staple-supporter a passes, said slot allowing said staple-supporter to move laterally independent of the arm a'.

' A suitable spring I)" supports the staplesupporter a in its normal position, and the arm a is forced toward the case D, so as to carry the staple-supporter into the path of the staple-driver f by the expansive force of a spiral spring b surrounding the outer end of a bolt 01'', which passes through an aperture in the arm a' and is fastened to the case D, said spring bearing at one end on a nut 01 on the outer end of the bolt and at the opposite end on a washer seated on the exterior of the arm. v

A set-screw d" passes through the arm a and is adjustably connected thereto to cause it to project from the inner side thereof, so that, when the staple-driver is raised to its utmost elevation and the arm a is in its normal position, the aforesaid set-screw enters an orifice in the case D and pushes the anvil a to its requisite position for carrying the next wire blank under the staple former and driver.

The operation of the described anvil and staple-supporter is as follows: The stapledriverfin descending to drive the staple into the book supported on the table F, forces the anvil at out of the way and into the case D sufficiently to bring the slot 1) of said anvil in range with the wire-guiding groove g in the case and thus permit the next wire blank to enter the slot 1), as illustrated in Figs. 15 and 16 of the drawings. The staple-driver then rises and allows the anvil a to move back to its normal position, as shown in Fig. 14 of the drawings, and in this movement said anvil carries the wire blank to a position directly under and parallel with the bottom edges of the staple-forming plates 6 e", which edges are provided with grooves by which to obtain a hold on the wire blank. The staple-former then descends and by straddling the anvil ait bends down the end portions of the blank and thereby forms the staple. As soon as this is effected the driver f descends, and in pushing the anvil a outof the way the staple becomes released from said anvil and is forced down into the book supported on the table F. In this operation the grooved edges of the plates 6" e" serve to hold the shanks of the staple closely to the sides of the staple-supporter a and guide said shanks so as to prevent them from bending. In this driving operation the staple-supporter yields to the downward pressure of the driver, as represented in Fig. 16 of the drawings.

In order to prevent excessive inward thrust of the wire blank under the staple-driver and former bythe released anvil a, we connect to the plates 6" e vertically movable stops 72, preferably of the form of metal strips disposed immediately back of the staple-guiding grooves of the plates 6" e" and sliding in vertical grooves 77. in said plates, as shown in Fig. 19 of the drawings. A suitable spring h" connects the metal strip h to the plate 6 and holds the strip normally in a position to project below the bottom of the plate and arrest the lateral thrust of the wire blank imparted to it by the anvil a. In the descent of the staple-former the strip or stops h readily yield to the contact with the book so as to obviate injuring the same. To hold the wire blank 'in position in the slot 17 of the anvil at until the staple-former has obtained a proper hold on said blank, we place horizontally across the slot 1) a wire-detaining finger c, which extends through to the back of the hanger ct" and is movable vertically, and formed cylindrical or with a rounded or beveled under side to allow the blank to pass under it. This finger we preferably connect to the lower end of a plate 0, which slides longitudinally in a vertical guide-groove in the outer side of the hanger a and receives downward pressure by a spring 0''.

E represents the spool upon which is wound the wire from which the staples are formed.

YOU

Said spool is preferably mounted on the head A. .A guide E conducts the wire to the feeding mechanism which is operated automatically and in harmony with the operation of the staple-former and staple-driver. Said feeding mechanism consists of two rollers R R, disposed in the same plane and with their peripheries in sufficient proximity to each other to grip the wire passing between them. Said rollers have affixed to them intermeshing gears t' c" by which they are caused to rotate in unison. The gear-wheelt' is fastened to a hollow shaftj, which is journaled on a supporting-shaft j','passing longitudinally through said hollow shaft and mounted at one end in a suitable bearing on a bracket 7c, secured to a on a bracket G fastened to the back of said plate-extension, as more clearly shown in Fig. 8 of the drawings. Tothe hollow shaft is also firmly-secured the ratchet-wheel G, and on the shaftj' is loosely mounted the gear-wheel H, meshing with a gear H, which is either rigidly attached to or formed integral with the cam-wheel B and thus partakes motion from the same. To the gear H is connected a pawl Z, which by engagement with the ratchetwheel Gtransmits rotary motion to the feedroller R, which by aid of the companion roller R draws along the wire. A gnidel conducts the wire from said feed-rollers to the cutter, which severs the wire and forms the blanks for the staples as hereinafter described.

'In order to allow the wire to be fed at. intervals and periods of different lengths and 7 thus form blanks for different sizes of staples to be formed, we employ a suitable automatic feed-regulating device for controlling the feeding mechanism. Thisfeed-regulatingdevice we prefer to form as follows: The rear bracket G is either formed with or has rigidly attached to it a shield J having a flange which covers about one-half of the peripheral face of theratchet-wheel G, and to the supporting shaft j is fastened another shield J, which also has a flange extending across and about half-way around the periphery of the ratchet wheel, as more clearly shown in Figs. 6 and 8 of the drawings. The pawl Z has pivoted to its side a roller Z or is otherwise provided with a suitable projection which during the wheel not covered by the stationary shield J said ratchet-wheel is permitted to be turned a corresponding shorter or longer distance by the pawl and the motion of the feed-rollers R R is varied accordingly.

by which to turn said shaft, and in connection with said lever we employ a graduated seg mental scale S, which is concentric to the shaft j and traversed by the free end of the lever. Said scale is formed of a segmental row of sockets n n in the face-plate A, and the free end of the lever has projecting from it a spur adapted to enter the sockets. The lever which also serves as an indicator may be made flexible to automatically force the spur into the socketor the spur may be connected to the lever movabl y to and from the scale. This scale is made to correspond to a scale Son the nut N by which the booksupporting table F is raised and lowered to allow the staple-former and staple-d river to operate on books of diferent thicknesses; said table being mounted on a screw N passing through the nut N .which is seated in a recess in the arm A" and is thereby supported, as shown in Fig.1 of the drawings. An indicator n attached to the arm A points to the scale S. p

The elevation of the table required for operating on the book to be placed thereon is determined by insertingthe edge of the book between the under side of the arm A and a collar K attached to the lower end of the screw and then turning the nut N until the inserted edge of. the book is in intimate contact with the said arm and collar. Then by setting the lever in to a socket to opposite a number cor responding to that pointed at on the scale S by the indicator n, the before-described movable shield J is set so as to regulate the wirefeeding mechanism for forming staples of the requisite. lengths for binding the book.

In order to facilitate the operation of introducing a newly-supplied wire between the feed-rollers R R, we pivot the roller R to a supplemental face plate R, the shape of which is more clearly shown in Fig. 20 of the drawings, and which is hinged at 15 to the lateral extension of the faceplate A and is in the same plane therewith. Said supplemental plate can be swung away from the face-plate to separate the two rollers sufliciently to allow the wire to be easily placed between them.

For locking the supplemental plate on the face-plateto retain thefeed-rollers in their drawings.

p p represent two pairs of rollers which straighten the wire and guide itto the feedrollers R R. One pair 19p of said guiderollers is pivoted to the faceplate A and the other pair pp is pivoted to a bracket g, which is mounted on the plate R and is adjustable toward and from the rollers 19 p to regulate the distance between the two pairs. Said adjustability we preferably attain by providing the horizontal foot of the bracket with a longitudinal slot q for the reception of the screw g", by which the bracket is clamped on the plate R, as shown in Figs. 2 and 9 of the drawings. To render the adjustment more accurate, we employ aset-screw 7, which passes through a screw-threaded eye in a lug 1" formed on the plate B", said screw bearing on a similar lug 7', formed on the bracket g.

8 denotes the cutter which severs the wire and forms therefrom the blanks tobe bent into the form of staples. In order to permit said cutter to be adjusted in its position to leave the blank lying with the center of its length central on the anvil a, we place said cutter on a suitable carrier L, which is connected to the faceplate A and adjustable in relation to its distance from the anvil a. To effect this adjustment of the cutter-carrier simultaneously with the hereinbefore described adjustment of the stop-motion of the feeding mechanism, we pivot the carrier L in a suspended position to the face-plate A' and connect it to the feed-regulating lever m by means of a rod m, connected at one end to the carrier L and having on its opposite end a rack m" engaging a toothed segment m, which is concentric with the shaft j and either attached to or formed on the lever m to turn therewith.

The lower portion of the carrier L has eX- tending horizontally through it a wire-guiding channel 15, in one end of which is fastened the stationary cutter 15, preferably of the form of a tubular plug, which is screw-threaded externally and inserted into a correspondingly screw-threaded socket in the carrier and in line with the channel 25. The outer face-of said plug is flush with the exterior of the carrier L to allow the movable cutter to pass across said stationary cutter.

The object of the described construction and attachment of the stationary cutter is to allow it to be removed when required for repairs or renewal.

The movable cutter s is attached to a plunger s, sliding in a vertical guide 8" formed in the carrier L, as shown in Figs. 10 and 11 of the drawings. Said plunger is intermittently depressed by means of a tumbler o, pivoted in the face-plate A" and provided at its inner end with a lug 2), which is in the path of a cam w formed or attached to a rotary wheel, preferably the wheel B, as shown in Fig. 10 of the drawings, by which cam the tumbler is partially turned in one direction on its axis during the rotation of the wheel. The outer end of the tumbler has projecting from ita finger'v by which it bears on top of the plunger 3'. The form of the tumbler is clearly illustrated in Fig. 12 of the drawings. The employment of the aforesaid tumbler is resorted to for the purpose of transmitting motion of the cam w at one side of the faceplate A' to the knife-carrying plunger situated at the opposite side of said plate.

By operating the tumbler t) by the cam 10, attached to the wheel B, which actuates the wire feeding mechanism, staple-former, and staple-driver, the cutter sis caused to operate positively in unison with the aforesaid mechanism and parts deriving motion from said wheel.

To prevent the wire blank from springing away from the side of the cutter at the moment said blank is severed from the wire, We employ a yielding detent T in the path of the end of the wire so as to come in contact therewith and hold the blank back to abut with its opposite end againstthe side of the cutter s.

suspended position in a recess T in the case D and havingits lower end in the path of the wire, as shown in Fig. 13 of the drawings.
